Objective: The aortic valve complex is an anatomical and a physiological junctional structure. Its root morphology presents a complex junctional structure extending from the ventriculoarterial to sinotubular junction and consisting of three Valsalva sinuses and cusps to achieve an optimal physiological pump function of the left ventricle. In this research study, a geometric model of the aortic complex was created allowing input to make it applicable in cardiac surgery. Material and Methods: The aortic valve has a consistent shape that can be described mathematically, dependent on the root diameter. The geometric model of the mathematical structures was developed with the Bézier technique, that is, by obtaining a curve or surface that can be controlled by the designer. Primarily, the boundary Bézier curves of the aortic valve tissue to be modeled were determined, which then revealed a frame of the surface. In the next step, within this frame, aortic leaflets were obtained by interpolations. Results: After the threedimensional (3-D) computer-aided design display was finished in Blender, the aortic valve complex was exported as a stereolithographic document and a model of the aortic root was printed using polylactic corrosive fibers. Conclusion: Geometric modeling of heart valves obtained by threedimensional imaging can be used in the production of customized prosthetic valves. Evaluation of the anatomical structure features of the heart valves using geometrical modeling could be developed and adapted for other heart valves.

Amaç: Aort kök morfolojisi, Valsalva sinüsleriyle aortik küspisler olmak üzere ventriküloarteriyel bileşkeden sinotubüler bileşkeye uzanarak sol ventrikül fizyolojik pompa işlevi için optimal yapıyı oluşturur. Aort kapak kompleksi, anatomik ve fizyolojik bir kavşak yapı şeklindedir. Bu araştırmada, aort kapak kompleksinin görüntüleme verileri kullanılarak, kardiyak cerrahiye uyarlanabilir geometrik aort kapak modeli oluşturulmaktadır. Gereç ve Yöntem: Aort kapağı, kök çapına bağlı olarak matematiksel olarak tanımlanabilen tutarlı bir forma sahiptir. Matematiksel yapıların geometrik modeli Bézier tekniği ile yani kurgulayıcı tarafından kontrol edilebilen bir eğri veya yüzey elde edilerek geliştirilmiştir. Öncelikle, modellenecek aort kapak dokusunun sınır Bézier eğrileri belirlenmiş, daha sonra yüzeyin bir çerçevesi ortaya çıkartılmıştır. Bir sonraki aşamada bu çerçevede, interpolasyonlarla aort yaprakçıklarınnın modellenmesi gerçekleştirilmiştir. Bulgular: Üç boyutlu (3-B) bilgisayar destekli tasarım gösterimi Blender’da tamamlandıktan sonra, aort kapak kompleksi stereolitografik bir dokümana dönüştürülerek, aort kökü modeli polilaktik aşındırıcı lifler kullanılarak basıldı. Sonuç: Üç boyutlu görüntüleme ile elde edilen kalp kapakçıklarının geometrik modellemesi, özel boyutlu protez kapakların üretiminde kullanılabilir. Kalp kapakçıklarının anatomik yapı özelliklerinin geometrik modelleme kullanılarak değerlendirilmesi geliştirilebilir ve diğer kalp kapakçıkları için de uyarlanabilir.
